Hardware Security Fiasco: The Latest

Microsoft rolled out Windows 10 cumulative update KB4056892 yesterday as an emergency patch for systems running the Fall Creators Update in an attempt to fix the Meltdown and Spectre bugs affecting Intel, AMD, and ARM processors manufactured in the last two decades.

But as it turns out, instead of fixing the two security vulnerabilities on some computers, the cumulative update actually breaks them down, with several users complaining that their systems were rendered useless after attempting to install KB4056892.

Our readers pointed me to three different Microsoft Community threads (1, 2, 3) where users reported cumulative update KB4056892 issues, and in every case the problem appears to be exactly the same: AMD systems end up with a boot error before trying a rollback and failing with error 0x800f0845.

In the wake of The Register's report on Tuesday about the vulnerabilities affecting Intel chips, Chipzilla on Wednesday issued a press release to address the problems disclosed by Google's security researchers that afternoon.

To help put Intel's claims into context, we've annotated the text. Bold is Intel's spin.

Meltdown and Spectre are two different—but equally nasty—exploits in hardware. They are local, read-only exploits not known to corrupt, delete, nor modify data. For local single user laptops, such as Librem laptops, this is not as large of a threat as on shared servers—where a user on one virtual machine could access another user’s data on a separate virtual machine.

As we have stated numerous times, security is a game of depth. To exploit any given layer, you go to a lower layer and you have access to everything higher in the stack.

While an Intel spokesperson told CBS Marketwatch reporter Jeremy Owens that the trades were "unrelated" to the security revelations, and Intel financial filings showed that the stock sales were previously scheduled, Krzanich scheduled those sales on October 30. That's a full five months after researchers informed Intel of the vulnerabilities. And Intel has offered no further explanation of why Krzanich abruptly sold off all the stock he was permitted to.

Ubuntu, perhaps the most popular Linux distribution, on the desktop, which has multitudes of other distributions depending on it to send out security updates, has announced that it will update the kernels of all supported releases in order to mitigate the newly publicly disclosed Meltdown and Spectre vulnerabilities, by January 9th.

Security researchers revealed disastrous flaws in processors manufactured by Intel and other companies this week. The vulnerabilities, which were discovered by Google’s Project Zero and nicknamed Meltdown and Spectre, can cause data to leak from kernel memory—which is really not ideal since the kernel is central to operating systems and handles a bunch of sensitive processes.

Intel says that it’s working to update all of the processors it has introduced in the last few years. “By the end of next week, Intel expects to have issued updates for more than 90 percent of processor products introduced within the past five years,” the company said in a statement today.

After a rollercoaster day of speculation on Jan. 3 about a severe Intel chip flaw, Google's Project Zero research team revealed later that same day details about the CPU vulnerabilities.

The CPU flaws have been branded as Meltdown and Spectre and have widespread impact across different silicon, operating system, browser and cloud vendors. The Meltdown flaw, identified as CVE-2017-5754, affects Intel CPUs. Spectre, known as CVE-2017-5753 and CVE-2017-5715, impacts all modern processors, including ones from Intel, Advanced Micro Devices and ARM.

New reports have surfaced suggesting that there might be a major security flaw with Intel processors launched in the last decade. The harsh part is that patching the issue might slow down the performance of the CPU by up to 30 percent. Intel hasn't put out an official statement yet, but Linux Kernel patches are being pushed out to all users.

KDE Says Its Next Plasma Desktop Release Will Start a Full Second Faster

According to the developer, the upcoming KDE Plasma 5.13 desktop environment release will start a full second faster than previous versions because of the removal of the QmlObjectIncubationController component, which apparently slowed down the entire desktop, and promises to let users pin apps on the panel that contain spaces in their desktop file names.
Goodies are also coming to the upcoming KDE Applications 18.04 software suite this spring, which makes creating of new files with the Dolphin file manager instantaneous, improves drag-and-drop support from Spectacle to Chromium, and lets users configure the Gwenview image viewer to no longer display the image action buttons on thumbnails when they hover with the mouse cursor over them.

Intel Coffee Lake OpenGL Performance On Windows 10 vs. Linux

For those curious about the state of Intel's open-source Mesa OpenGL driver relative to the company's closed-source Windows OpenGL driver, here are some fresh benchmark results when making use of an Intel Core i7 8700K "Coffee Lake" processor with UHD Graphics 630 and testing from Windows 10 Pro x64 against Ubuntu 16.04.3 LTS, Ubuntu with the Linux 4.16 Git kernel and Mesa 18.1-dev, and then Intel's own Clear Linux distribution.
